This is the tower space heater oscillates 90º to distribute heat faster and more evenly throughout a room. In tests by The Hammacher Schlemmer Institute, this heater raised the ambient temperature of a 216' sq. room by 5.10º F in only 15 minutes, far superior than lesser models that could only muster a 0.8º F increase. A switch in the base immediately cuts power when it is tipped over, and when a towel was draped over the heater to simulate overheating it turned off in less than five minutes. An integrated thermostat automatically turns the heater on or off when the room temperature reaches preset thresholds and an internal filter removes airborne impurities. Includes two AAA batteries for remote control. 27 1/2" H x 10 1/2" Diam. (6 1/2 lbs.)
